by Corey on 12/28/2015 Recently fired quite a few hundred rounds with my S&W M&P Defend. I had jams with nearly just about every clip and a number of other misfires. I'd just cleaned the gun ahead of use but weapon jammed at the time I went through a clip. Do not squander your money on this ammo. Stick with brass.Ready to load up with 9mm steel-sit
